element nitrogen facts

It may be noted that lithium reacts with N 2 to form lithium nitride but sodium does not form sodium nitride...

Discovery - Daniel Rutherford, a Scottish Physician, discovered nitrogen in 1772. But it was Lavoisier, who proved that nitrogen is an element and that it was not a supporter of combustion and respiration. He called it 'azote' meaning 'no life'. The name 'Nitrogen..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing, and produced by man..

Group 15 of the Periodic table includes five elements namely nitrogen (N), phosphorus (P), arsenic (As) antimony (Sb) and bismuth (Bi). This group is regarded as nitrogen family. There is a transition from non-metallic to metallic character as we go down the ..

Elements of group 13 to 18 of the periodic table are collectively called 'p' block elements. The general electronic configuration of these elements is ns 2 np 1 - 6 . They involve the filling up of 'p' orbitals of their outermost shells, when their 's..

Nitrogen is present in the elemental state in the atmosphere to the extent of about 78% by volume. Nitrogen is important for life processes in all living organisms. But, free nitrogen cannot be directly assimilated by the living cells. Therefore, it is desir..

Nitrogen gas (dinitrogen) is chemically non-reactive at ordinary temperature due to: Its small atomic size. Its high bond order. The N-N bond in the N 2 molecule has a formal triple bond character. The dissociation constant is extremely small and ..
